I have to start this with a big thanks to Erik at http://backstreetper.com/ for the time, knowledge, and super safe tune. I will have zero hesitation laying into this thing every time I get it out.

 

Well after fixing some stuff, finding more broken stuff, and adding more zip ties, we managed to make some power pulls.

 

On gate-8psi-540whp

 

at 14.8 psi (202 logged KPA) it made 736whp/654 trq. Full spool happened around 4800 in 4th (410 rear gear/T56). Honestly surprised how much HP per PSI this think was picking up. It was already a long night and we had not drank enough to throw 20+psi at it, so we called it a night. But, I think the stock LS1 record would have been in serious jeopardy!

 

 

 

The car comes on boost like its making 1000whp. It runs and sounds ridiculous. I am 100% happy with the outcome, and still have a lot of cleaning up and improving to do with the bay and the harness. This is still a 100% bone stock Ls1, so I think it would be good to shoot for 850+ when I install my "trash-Cam" and a set of valve springs.

 

Videos soon-my go pro died but I think Jerry got a few at full song.

that car is beautiful before you started, how much?

 

Thanks.

 

If you asking about initial investment I traded for a 01 Civic with $1000 on top (I had about $1800 into the civic was t belt victim) and it came with an Ls1, hacked truck harness, T56, and many spare RX-7 parts. The car was a swap project abandon 7 years ago and sat ever since.

PM me a price. :)

 

No PM needed. 11k would take it home since I am not looking to sell it and time soon, but if someone had to have it....

 

If your in the market another really nice FC that's ready to race

Thanks for the inspiration man. Cant wait to throw a 76-80mm single or YSi on the C5 now. I'm going after that stock LS record too, lol.

 

Thanks- and do it! I told Ryan we should have a dyno day together and stay until someone windows a block. :)

736 @ 14psi???? What size turbo is on this thing. It took me over 20psi to get 703. Granted it was on a auto but I still find that hard to believe?????

Twin Billet 67's

 

In all fairness it was closer to 15 than 14, I am just quoting the KPA on the log.

 

You are running a dinosaur tech turbo through an Auto- it is what it is! Call Chad back if you want a pair of much more efficient options :)
